i would suspect it is your fuel lines knocking against the chassis.  Quite common and an easy fix, search on here to find thread

No knocking fuel lines on 07 GT  TDI - yes on GTI that would be a good shout!

If your saying it's an engine noise my money would be a faulty injector for the symptoms you've described hot or cold or the tank fuel pump beginning to fail!

Had similar issue, turned out to be a worn belt tensioner.

Get your alternator clutch pulley checked. I have a similar issue where I had replaced the tensioner and belt, but the noise came back 7-8months later. Realised that the clutch pulley was jammed. This causes extra stress on the tensioner pulley and causes it to wear prematurely. For me the sound is a very pronounced intermittent tappett noise in the cabin. Kinda subsides in neutral and under a little load
